1047. Root has assumed a peculiar form

In a few cases, where the root has assumed a peculiar form before the causative sign — as by the addition of a p or ṣ (above, 1042 i ff.) — the reduplicated aorist is made from this form instead of from the simple root: thus, atiṣṭhipam from sthāp (stem sthāpaya for √sthā. Aorist-stems of this character from quasi-roots in āp are arpipa (√ṛ), jījapa orjījipa, jijñapa or jijñipa, çiçrapa, tiṣṭhipa, jīhipa; the only other example from the older language is bībhiṣa from bhīṣ for √bhī.
